    Description / Table of Contents: The Electronic Structure of Highly Symmetrical Compounds of the Lanthanides and Actinides. X. The Crystal Field Splitting Pattern of Cs2NaPrIIICl6 in the Low Energetic RegionBy means of the techniques of the electronic Raman effect, absorption and emission spectroscopy the low energetic crystal field splitting pattern of Cs2NaPrCl6 could be determined. Using the parameter set: F2 = 317.3, F4 = 54.4, F6 = 6.35, ζ4f = 762.8, B°4 = 271.9 and B°6 = 16.8 cm-1 a good agreement between observed and calculated signals has been achieved.
    Notes: Mit Hilfe der Arbeitstechniken des elektronischen Raman-Effektes, der Absorptions- und Emissionsspektroskopie konnte das Kristallfeld-Aufspaltungsmuster von Cs2NaPrCl6 im Niederenergiebereich bestimmt werden. Unter Verwendung der Parameter: F2 = 317,3, F4 = 54,4 F6 = 6,35, ζ4f = 762,8, B°4 = 271,9 und B°6 = 16,8 cm-1 konnte gute Übereinstimmung zwischen berechneten und gemessenen Werten erzielt werden.

    Description / Table of Contents: Electronic Structure of Highly Symmetrical Compounds of the Lanthanides and Actinides XIII. Cs2KYF6- a Lattice which is Especially Suitable for Spectroscopic Studies of Fluoro-ElpasolitesThe preparation of Cs2KYF6: Eu, Tb is described in detail and the particular suitability of the resulting products for spectroscopical measurements is proved by their well resolved bands in the fluorescence spectra. Following the interpretation of the emission spectra of Cs2NaEUCl6 and Cs2NaTbCl6 the observed O—O transitions of magnetic dipole and electric Quadrupole Character respectively can be assigned. A closer analysis of the vibronic transitions Cs2NaY0,99Eu0,01F6allows a determination of the energies of some vibrational states of odd parity.
    Notes: Die Präparation von Cs2KYF6: Eu, Tb wird in Einzelheiten beschrieben und die Eignung der resultierenden Produkte für spektroskopische Messungen durch deren gut aufgelöste Banden in den Fluroeszenspektren belegt. In Anlehung an die Interpretation der Emissionspektren von Cs2NaEuCl6 und Cs2NaTbCl6 werden die beobachteten O—O- Übergänge von magnetischem Dipol-und elektrischem Quadrupolcharakter zugeordnet. Eine nähere Analyse der vibronischen Übergänge von Cs2NaY0,99Eu 0,01F6 gestattet die Bestimmung der Energien einiger Schwingungszustsände ungerader Parität.
